Title

(EN) Joining metal wire filaments to nonwoven structures for producing honey-comb bodies

(ZH) 将金属丝接合成用于制造蜂窝体的纤维网的方法

Abstract

(EN) The invention relates to a method for producing a nonwoven structure (1) comprising metal wire filaments (2) by carrying out the following steps: a) producing a layer (3) comprising wire filaments (2); establishing first integral joints (4) between at least a part of the metal wire filaments (2) using a first joining method; c) establishing second integral joints (5) between metal wire filaments (2) using a second joining method. The invention also relates to corresponding nonwoven structures and to possible uses thereof, for example in the exhaust gas treatment of motor vehicles.

(ZH)

用于制造包含金属丝(2)的纤维网(1)的方法包括至少下列步骤：a)形成具有金属丝(2)的层(3)；b)用第一接合方法在至少一部分金属丝(2)之间产生第一材料接合连接(4)；c)用第二接合方法在金属丝(2)之间产生第二材料接合连接(5)。此外，说明了相应的纤维网和例如在机动车辆的排气处理装置中的有利的应用可能性。
